Add ESP32 Boards to Arduino IDE

Open Arduino, select File -> Preferences.

Add the following URL to the "Additional Boards Manager URLs" section:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Restart Arduino.

Go to Tools -> Board -> Boards Manager...

Search and install the esp32.

After installation, select "".

Configure Example Code

Wiring

Note: do NOT use the GND pin near U0T pin (the one labeled "GND/R"). That pin does not connect to ground for some of the boards.

After plugging in the debugger, select the corresponding COM port. No need to change other settings.

After upload, remove the IO0 jumper wire, open Serial Monitor, and click reset button, located at the back of the board.
